Jihadi John’s threat to IS enemies

Islamic State’s Brit-born executioner has vowed his enemies will suffer the same fate as the victims he has beheaded.

The killer is thought to have surfaced on his own Twitter account.

Security services are analysing it but experts believe it could be genuine.

It is linked to Twitter accounts operated by several known Brit IS fighters in Syria.

On his feed Jihadi John said: “Instead of sending me 1000 tweets per day, buy a ticket and come here. We have a knife, an orange jumpsuit and a camera waiting for you.”

Intelligence experts had believed the killer with the distinct London accent that has ­become the voice of IS may have been injured in a US air strike close to the Iraq/Syria border in November.But a tweet this week read: “I’m very much alive, and even when I’m not, Jihad will continue.

“The nightmare won’t stop.”

Jihadi John is wanted for the murders of Brit aid workers Alan Henning, 47, and David Haines, 44, and Americans James Foley, 40, Steven Sotloff, 31, and Peter Kassig, 26.

RECORDING: New recording of Japanese hostage Kenji Goto is being analysed [GETTY]

Yesterday a report revealed Brit jihadi brides in Syria are working as “recruiting sergeants” for IS and getting pregnant to breed a new generation of fighters.

Japan says it is investigating a purported new voice recording of hostage Kenji Goto.

The person in the recording says a Jordanian pilot hostage will be killed unless an Iraqi prisoner held by Jordan is freed by sunset.

In Tokyo, a spokesman said Japan was doing its utmost for the release of Goto.
